Add rows to a table, based on data from an existing column

Sorry, my first post and I'm new to Power BI. One table, the second table is how I want the first table to look. The first table is a report on hazard assessment forms completed by workers, the one column contains the names of workers involved in the hazard assessment. I want totals for each work involved in the hazard assessment process, not just those who completed the form. For if 50 hazard assessments were completed, and 12 additional workers were involved in those 50 HA, the number of rows in the table should be 62.
